People can get pregnant not under their own terms (rape,etc) or at a time they are not physically able to raise a child (teenage years, poverty, etc) so they would just be putting the child in a bad place if the parent wasn’t allowed to choose to abort because the parent might not be able to support a good life for the child or could struggle caring for the child as they are a constant reminder of a traumatic situation. In the end, it’s their body and them that has to experience pregnancy and everything that comes with it so it should be their choice
